There will be days, weeks, months, even years when you feel no one is on your side. You will feel that some people are going out of their way to be mean or to belittle you. You will feel like you have no place on this earth where you can just be you.
When this happens to you have a clear mind and a soft heart. It might very well be the case that some people are out to get you or it might just be that their interest in you doesn't match your interest in them. Indifference is a difficult thing to get over, trust me It might be that you didn't do anything to deserve the feelings you are having or it might be that you did do a thing or two.
Whatever the case is, first think. It will help to breathe. Is the situation you are in unhealthy or unhappy and of need of a change? Would changing anything really make things better? How much of what you are feeling is about you vs. the situation vs. the people you are around. Think through it, it's really important. Some things will naturally pass and some things won't. If you have a friend who is pulling you into things that are bad for you then it might be time to get a new friend. Or it might not. The situation will tell you. Think it out. Talk it out. Keep a clear mind even if those around you cannot.
The second thing to do is to keep a soft heart. This can be really hard to do if you feel you are under attack or that no one truly loves or understands you. But you must work at keeping your heart full of love and open to life. If you let it go hard then you will have a hard time to get it back. If someone does something wrong to you or slights you in some way, instead of hating them or yourself try to feel for them. Feel for yourself. Take a moment and just let the feelings in without judging them. There will be some people that you may need to distance yourself from because they can hurt you so much emotionally. In those situations, protect your soft heart so that it available to all those other people in the world.
Let all those other people with soft hearts and clear minds be your comfort. It might be that your circle of friends with soft hearts and clear minds is really small, even just you, but that will be enough to get you through the tough times and able to appreciate the sunshine on the other side. Don't give up, struggle for love and appreciate it when you have it.
